There is a HUGE difference between the two! A detail service consists of 1-3 trained detailers focusing solely on your vehicle for a scheduled period of time to provide your vehicle with the best care. Services are provided with care to prevent any damage, while a car wash is created to quickly get you in and out. Whether it is worth it to you or not entirely up to you. But if your goal is to care for you vehicle properly maintaining its appearance and value, a detailing service is what you're looking for.
